About

LayerLog

Features
Read full description

LayerLog is a print log for 3D printing that stops the same failure from happening twice. Log what you print, how it turned out, and the settings that worked, then watch your success rate climb. No account, no tracking. Everything lives on your device and in your private iCloud, and syncs across your iPhone, iPad, and Mac. WHAT LAYERLOG DOES Print log with result and photos. Record the model, material, printer, spool, and profile, mark it a success, partial, or fail, and add a photo and a quality rating. Settings that worked. Save slicer profiles per filament and model type: nozzle and bed temperature, print speed, layer height, retraction, flow, and fan. Filament stash math. Track every spool with grams left, drawn down on its own as you log prints, plus cost per print from what the spool cost you. Failure notes with fixes. Tag a failed print with its cause and the fix that cleared it, backed by a built-in guide to ten common FDM failures with symptoms and steps. A success rate you can see. A success rate for the last 30 days, outcomes by week, filament by material, and success by material, all drawn as charts. Maintenance reminders. Set an interval for each printer task and LayerLog tracks due and overdue, with an optional local reminder per task. SYNC AND EXPORT LayerLog syncs across iPhone, iPad, and Mac with iCloud. Export a printable PDF report or CSV files of your prints, filament, and profiles whenever you want your data elsewhere. FREE VS PRO Free includes 15 prints with every tool: results, photos, spool tracking, cost per print, the fix guide, and maintenance reminders. Pro unlocks unlimited prints and unlimited settings profiles, plus the PDF and CSV exports. LayerLog is a personal log for your own records. Print, log, adjust. The next print goes better. LayerLog Pro subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Payment is charged to your Apple Account. Manage or cancel anytime in Settings.
